Talk:Boiler repair

We could do with a collection of boiler-specific faults somewhere. This should probably be in an article of its own, but for the moment I'll use this as a notepad for snippets as they come in --John Stumbles 13:02, 23 February 2007 (GMT)

Keston C25 ignition failures

one common reason for this is the electrodes moving apart. Do not try and bend them back when cold. Someone here said that you can straighten an electrode when hot (hold in gas hob flame) but I've not tried this myself.

The biggest downside to Kestons seems to be parts availability

Generic parts in boilers

Could do with info on what parts of what boilers are replaceable by standard or generic parts.

• BES do a diaphragm repair kit for which they have scant information. Would be useful to have some idea which boilers it's compatible with.
• Many boilers use standard Grundfos (or other) pumps and one can just replace the heads (though on some - such as Potterton Performas - you can't, even though they look from the outside like standard Grundfos heads).

Must-also-replace parts

Some repairs involve replacing various O-rings, fibre washers etc. Would be good to know which, and if generics are OK.
